The Wizard of the Great Power: Turn in the Double Door at the Beginning

Traveling through the world of Harry Potter and becoming a new Ravenclaw born as a Muggle, Ryan Walker awakens the double portal that connects the wizarding and Muggle worlds. When all the time-travelers wanted to grab the golden finger and secretly develop, Ryan backhanded a "Feasibility Report on Introducing Industrialization into the Magical World to Improve Comprehensive Strength" and submitted it directly to the Ministry of Magic together with the secret of the double-travel door! Fudge: "Producing ten thousand bottles of healing potion a day? This is impossible!" Lucius Malfoy: "Can vulgar Muggle gadgets be compared with noble magic?" When Voldemort returned with an army of Death Eaters and faced an army of Aurors equipped with enchanted assault rifles and wearing Kevlar leather armor, he was completely lost in thought. Voldemort: "Dumbledore! Do you call this magic?" Ryan Walker stood at the top of the magic industrialization assembly line and smiled slightly: "No, sir, times have changed. This is called truth."
